But the alloying additions, which are present in aluminium alloys especially magnesiumusually aggravate the metallurgic conditions of aluminium bonding. However, in the technological bending tests, bending angles within few sppawalnictwo have been achieved, with ambrkziak small dependence on the diameter of the bending mandrel. Abstract PDF References Article Recommendations Abstract In this article results of studies on cracks formation susceptibility in braze-welded joints of thin aluminum sheets and double-sided zinc galvanized steel sheets for car body parts made by laser brazing with high power diode laser ROFIN DL and CMT MIG-brazing, with ajbroziak material in form of powder and wire accordingly, were presented.

Using of such high diameters of the samples has been determined by the desire to achieve the most accurate approximation of the research for their utilitarian purpose.

Using resistance spot welding for joining aluminium elements in automotive industry

It has been stated that the joint was characterized by efficient tensile strength, if the width of the diffusion zone with intermetallic phases was 0. Despite the short time of the welding process and the high pressure during the upsetting sample no.

The microstructure in the bonding zone of the friction welded AlMgSi0. There are some additional factors, for example, coefficients of thermal expansion of welded materials and their melting temperatures, the knowledge of which is also necessary in the case of joining dissimilar materials [ 3 — 6 ]. Introduction The family of friction welding processes includes several methods, such as rotary friction welding RFWlinear friction welding LFWand the newest one, friction stir welding FSW.

In this article results of studies on cracks formation susceptibility in braze-welded joints of thin aluminum sheets and double-sided zinc galvanized steel sheets for car body parts made by laser brazing with high power diode laser ROFIN DL and CMT MIG-brazing, with filler material in form of powder and wire accordingly, were presented.

View of friction welded joints of AlMgSi0. In this article the comprehensive summary concerning technology of resistance spot welding of aluminium alloys was presented.

Friction Welding of Aluminium and Aluminium Alloys with Steel

The parameters of friction welding and strength properties of joints of dissimilar materials aluminium and aluminium alloys with steel or titanium. Effect of Cu-Ag-O electrode on resistance spot welding of aluminium alloy sheet. On the contact surface of AN40 alloy-nickel, on both sides, there was a visible discontinuous intermetallic phase separation Figure 24 b.

Their forming has influenced the various forms of the flash but has not caused an elimination of the intermetallic phases, on the surface of the materials being bonded Figure The view of a bond zone of friction welded AlMg3 aluminium alloy-austenitic steel joints light microscope, nonetched specimen, sample no.

The author has been conducting some intensive researches on the friction welding of such joints, partly presented in [ 13 ].

Compared to aluminium, magnesium is characterized by a higher diffusion coefficient and has significantly lower solubility in iron. Strength properties of the steel-aluminium joint, welded at various parameters according to [ 17 ].

Until now, it has not been possible to obtain any welded joints of chromium-nickel austenitic steel with AlMg3 aluminium alloy, with sufficient plastic properties for direct joining. During the friction welding of pure aluminum with austenitic steel intermetallic phases are formed, but the mechanical properties of the joints strength and the plasticity are still good and breaking occurs on the aluminum side.

The authors declare that there is no conflict of interests regarding the publication of this paper. Optimal welding parameters were determined by visual acceptance criteria. Furthermore, the microstructure and different properties of intermetallic phases, such as crack sensitivity, ductility, and corrosion resistance, are also very important.

For testing, they have used nonalloy carbon steel with a five times higher tensile strength than the tensile strength of aluminium. Braze-welding ; Intermetallic compound phase ; high power diode laser ; brazing.

For these reasons, on the welding surface of aluminium alloys that include magnesium, the intensive heterodiffusion and reaction-diffusion processes take place and cause the formation of the intermetallic phases.
